New era of dental imaging
Planmeca ProMax X-ray unit provides a wide range of extraoral imaging modalities:
- panoramic imaging for dental arch
- maxillary sinus imaging
- temporomandibular joint imaging
- 2D linear tomography
- cephalometry
Special programs for various diagnostic needs
|
Besides the Standard Panoramic program the following programs are offered: Interproximal panoramic program generates an image where interproximal teeth contacts are open, and it is most often used for caries detection. Orthogonal panoramic program produces an image with clearly visible alveolar crest for improved diagnostics, and it is ideal for periodontal imaging and implant planning.
|
|
Bitewing Panoramic program uses improved interproximal angulation geometry, resulting in an extroral bitewing image pair with very low patient dose.
|
|
In child mode, the imaging area and exposure values in all programs are reduced and in the panoramic program focal layer has been narrowed. This reduces the patient dosage by 35%, while providing full diagnostic information.
|
|
With the horizontal and vertical segmenting option, the exposure can be limited strictly to the diagnostic region of interest. Compared to full panoramic exposure patient dosage is reduced by up to 93%.*

The TMJ imaging programs produce lateral or posteroanterior views of open or closed temporomandibular joints. The imaging angle and position can be adjusted to correspond to the individual anatomy of each patient.
The standard Double TMJ programs produce mouth open and mouth closed images of the TMJs on the same radiograph either from lateral or from posteroanterior view. |
|
The optional Lateral-PA TMJ program produces lateral and PA views on the same radiograph and the Multi-angle TMJ programs produce radiographs with images from three different angles either from the lateral or posteroanterior view.
|
|
The sinus programs provide a clear view of the maxillary sinuses.

New opportunities with tomography
Automated and accurate tomography
The pre-adjustment of the position and angle of the tomographic exposure is done automatically according to the operator’s program and target selection on the main display. Fine-alignment using the smart positioning joystick is highly practical and intuitive. The dual laser beams indicate the exact site and orientation of the tomographic cut. An impression model of the patient’s dental arch can be used for easy and reliable fine-alignment of the position and the angle.
Ingenious Transtomography
The digital tomography option in Planmeca ProMax offers two imaging systems: digital linear tomography and Transtomography®.
The patented ingenious Transtomography® allows easier patient positioning and enhances the diagnostic value of the image. Transtomography® uses a multiple sweep method to produce linear tomography effect with a narrow X-ray beam. Transtomography® combines the translation movement with an oscillation movement where the centre of the rotation moves over the region of interest.*

Combined tomography
Combined tomography integrates cross-sectional and longitudinal views of the target on the same radiograph. The combined image is highly valuable in implant planning since the transversal and longitudinal views give three dimensional information from the target. This makes exact measurements possible.
|
|
Cross-sectional tomography
With cross-sectional tomography programs, 1–4 cross-sectional images can be taken either manually or using the versatile automatic programs on one radiograph. The automatic programs provide a series of adjacent images with adjustable intervals, multi-angle tomographic cuts, or targeted images of the sinus and the nasal cavity.
|
|
Longitudinal tomography
The longitudinal programs provide 1–4 longitudinal tomographic cuts on one radiograph either manually or with versatile automatic programs. The automatic programs provide series of adjacent images with adjustable intervals, multi-angle images, or special images of the sinus and the nasal cavity. Longitudinal slices are ideal for instance for third molar assessment and diagnostics of the temporomandibular joints.

Easy upgrades
Any existing film or digital Planmeca ProMax unit can be easily upgraded to Planmeca ProMax 3D or Planmeca ProMax 3D s unit. New imaging programs can be added with software upgrades ensuring superior maxillofacial radiographs every time and complying with future imaging needs. Film based Planmeca ProMax units can be digitised with Planmeca Dimax sensor systems
